SEAM FOR SEWED ARTICLES.

Specification of Letters Patent.

Patented May 2, 1916.

Application filed September 15, 1911. Serial No. 649,568.

To-aZZ whom it may concern:

Be it known that I, JOHN C. RINGE, a citizen of the United States,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements in Seamsfor Sewed Articles, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to an improvement in seams for sewed articles andparticularly to an arrangement of threads and fabrics for uniting andconfining the raw edges of two pieces of heavy fabrics, such as carpets,rugs, mattings, etc., the object being to provide a seam which shall bevery strong and elastic and which will effectually protect the rawedges, and present no objectionable ridge if opened or spread out flat.

In the accompanying drawing, figure is a top plan view of the improvedseam. In forming the improved double chain-stitch overedge seam, theneedle is first passed through the fabric carrying the thread 6 in theformation of the throughand-through stitches, when the needle isreturned slightly and forms the loop a followed by the looper carryingthe thread d the single through the loop a in the formation of the' loop6, which latter is held open by a suitable spreader to receive theneedle, which in the meantime has been returned to its copies of thispatent may be obtained for five cents each, by addressing the initialposition, in the formation of the next subsequent stitch, the loopermeanwhile retreating from the loop a when it reverses its movement andcrosses the edge of the fabric and forms the loop 0 in the path of theneedle as it is again moved to pierce the fabric, and as soon as theneedle has entered the fabric the looper retreats and re crosses theedge of the fabric, which effects the cross stitch and while performingthis last function it is again moved forward into the next subsequentlyformed loop a.

Claim A multiple thread overedge seam comprising, in combination withthe fabric, a thread 6 extending along the face of the fabric and havinga series of loops a passed through the same and another thread (Zpassing, in loop form, through the loops a at the opposite face of thefabric, the thread (i in its lead from one to the next subsequent stitchbeing crossed upon itself as it is passed from one to the opposite sideof the fabric forming the loops 0 encircling the loops (4 upon the firstnamed face of the fabric.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
